Answer:

A = 244.92 cm² or 78π

Step-by-step explanation:

A = πrl

r = 6 cm

l = 13 cm

π ≈ 3.14 cm

A = 3.14 × 6 × 13

A = 3.14 × 78

A = 244.92 cm²

Answer:

Step-by-step explanation:

A= 3.142 x r x l

r=6

l=13

total surface area = area of the curved section + area of the base

area of curved section = 6x13=78pi

aeea of base= 6x6=36pi

78+36=114pi = 358.1cm squared

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number
Brut [27]

if a number (lets say 'y' is that number) is equal to (I.e. y = )..mathematically

now y is equal to twice the smaller number ( lets say that the smaller number is 'x' ) plus (+) 3 . that brings us to the linear equation...

y = 2x + 3;

also the second part of the question says that the same number ( I.e. 'y' here ) is twice the sum of smaller number (I.e. '2x' here ) and 1.

which gives us 2nd equation I.e.

y = 2x + 1 ;

the question is to find the possible number of solutions for both these equation

to find solution means to find all those points or say numbers which would satisfy both these equations

now for the first equation..

lets say ( y = 5 ) this means ( 2(1) + 3 )

so the solution will be ( 1, 5)

now for the second equation..

we will proceed with whatever data we know..

I.e. we know that value of ' y ' is 5, as we assumed

putting value of y in 2 nd equation we get ( 2(2)+1 )

I.e solution will be ( 2, 5)

now what does this signify...?

it signifies that there is no such point that will satisfy both these equations simultaneously..

hence we can say that there is no solution possible for this situation.

Solve the problem.
yarga [219]

Answer:

39%

Step-by-step explanation:

Let's find the answer by using the following formula:

selling price=(paid price)+((paid price)*(percent markup)) which can be written as:

percent markup=((selling price)-(paid price))/(paid price)

percent markup=(27.80-20)/20

percent markup=0.39=39%

In conclusion, the percent markup is 39%.

Solve the system algebraically. Check your work.
Alika [10]
Hey there! :D

We can subtract the equations from each other. 

4x-3x=x

2y-2y=0

10-6=4 

x=4 <== that's all we have left of the equation

Now plug that in to solve.

3(4)+2y=6

12+2y=6

2y=-6

y=-3

Solution: (4,-3)

I hope this helps!
